RE: "Somewhat related, sometimes under very light acceleration it'll just go dead rich and stay that way until I lift off or give it more gas."
O2 & AMM sensors affect fuel stoic. If no intake air leaks, AMM might be a suspect.

ECU re-evaluates its map data; on older GM ECUs, it takes drive-time to change stored data points.
Belt Timing - I'll assume crank, cam, and distributor are in sync.
